How to grow potted lavender

Watering

Lavender does not like water stagnation near its roots. When water is poured thoroughly, wait until the soil is dry before watering again. The surface of the culture medium should be dry, the inside should be moist, and the leaves should wilt slightly. Watering should be done in the morning, away from sunlight, and water should not splash on the leaves and flowers, otherwise they will easily rot and breed red sea.

A continuously humid environment will cause the roots to not have enough air to breathe and grow poorly, or even suddenly die of the entire plant. This is often the reason for the failure of lavender cultivation.

illumination

Lavender is a full-sun plant that requires plenty of sunlight and a suitably humid environment. A full-sun environment is best. A plant can grow in half-sun conditions, but it will bloom more seldom. In summer, at least 50% of the sunlight should be blocked and ventilation should be increased to lower the ambient temperature. In winter, lavender can grow well on flat ground and should be cultivated under full sunlight.

temperature

Lavender is semi-heat tolerant and prefers cool weather, warm winters and cool summers.

Suitable temperature for growth: 15-25℃, can grow at 5-30℃.

Limit temperature: above 35℃. If the temperature is higher than 38-40℃ for a long time, the top stems and leaves will turn yellow.

In the northern winter, the plant goes dormant when the temperature is below 0℃ for a long time. During dormancy, the seedlings can withstand low temperatures of -20℃ to -25℃.

Pruning potted plants

Lavender flowers are rich in essential oils, and the flowers or inflorescences are used mainly. To facilitate harvesting, some small inflorescences in the early stage of cultivation may be flattened with large scissors. The newly grown inflorescences will be of uniform height, which is conducive to one-time harvesting.

Some varieties can reach a height of 90 cm. This method is also used to keep the plants short to encourage more branches, flowering, and increase the harvest.

Pruning is necessary after flowering. The plant can be pruned to two-thirds of its original size, which will make the plant firmer and more conducive to growth.

Pruning should be done in cool seasons such as spring and autumn, usually in spring. Pruning in autumn will affect the cold resistance.

When pruning, be careful not to cut the woody parts to avoid weakening and dying of the plant.
